1 Claim, 4 Drawing Figures FLOATING SUCTION NOZZLE My invention relatesto a floating suction head and in particular to a head which is capableof preventing the intake of non-floating debris from a liquid.

A conventional suction head is usually a strainer type device made ofmetal and functions while resting on the bottom of a pool pond or areato be drained. These devices are vulnerable to partial or completeclogging by mud, leaves water logged paper and cloth or other types ofnon-floating debris.

My invention is a floating suction head that eliminates the cloggingproblem not only in the head itself but also in the pump or suctionproducing device. It can be attached to any type hose, used for drainagepurposes, by means of a threaded coupling.

The invention will be described with reference to the accompanyingdrawings in which:

FIG. 1 is a perspective view of the nozzle according to the invention;and

FIGS. 2 and 3 are side elevational and bottom plan views respectively ofthe nozzle.

FIG. 4 shows another, embodiment.

The nozzle 1 comprises a top plate 2 of polyurethane foam and acylindrical housing 3.

Any standard suction hose 4 from a suction device is connected to a tube5 in the nozzle through a threaded coupling 6 to a strainer 9 throughwhich water is drawn. A counterweight 7 secured within the housing bybolts or rivets ll counter-balances the hose connection and causes thehead to remain level with plate 2 on the surface of the water 10 todrain'water into the intake system and assist in the stabilization ofthe head.

As shown in FIG. 4, intake ports 13 may be provided in the peripheralwall of the housing instead of, or in addition to the bottom strainer 9,and are likewise connected to the internal tube 5.

In operation, the nozzle may be used to empty a swimming pool 12, orsimilar body of water by placing the nozzle on the surface of the waterdrawing water into the nozzle through intake ports 9 and 13. Debris isexcluded by strainers.

Obviously other modifications are also possible.

What is claimed is:

1. A floating suction head comprising a submersible housing with acylindrical sidewall comprising a channel for the flow of liquid thereinand having a single discharge outlet rigidly coupled to said cylindricalsidewall, said outlet further comprising a lateral flexible tubeconnected to a suction device, inlet means including filter means fordrawing liquid into said housing, a counter-weight within said housingconnected to said cylindrical sidewall at a location oppositely spacedfrom said single discharge outlet and a buoyant plate of polyurethanefoam covering the upper end of said housing to floatingly support saidhousing and maintain its level in said liquid.
